Sarah Shahi is about to heat things up on NBC’s Chicago Fire…

The 32-year-old half-Spanish actress has signed on to appear in at least five episodes of the Dick Wolf-produced drama.

Shahi will guest star as Renee, a love interest for firefighter Kelly Severeid (played by Taylor Kinney). She’s already started shooting the role, and although there’s no airdate yet, viewers could possibly see her on screen by the end of the year.

For the last two seasons, Shahi has played mediator Kate Reed on USA’s Fairly Legal.

Shahi, who was recently named “TV’s sexiest star” by Maxim magazine, has also been seen in The L Word and Life.

She’s a former member of the Dallas Cowboy Cheerleaders and Miss Fort Worth USA.
